Hemant Kumar 27ac6136bc ANDROID: GKI: usb: Add support to handle USB SMMU S1 address
Update helper APIs to return physical address as well as
USB SMMU stage 1 address. Physical address is used to map
it to iova for remote processor. S1 address is used by xHC.
Get sg table containing one or mode page sized physical
address corresponding to S1 address for event ring, xfer
ring and xfer buffers using dma_get_sgtable(). Accordingly
update QMI response buffer for XHCI event ring, xfer ring
memory info and xfer buffer.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
